Application filed May 12, 1919.

To all 'whom t may concern.'

Be it known that I, CHARLES KERN, a citizen of the United States, residing at Los Angeles, in thecounty of Los Angeles and State of California, have invented newand useful lmprovements in Street-Surface De lineators, of which the following is a specification.

My object is to make a street surface delineator, and my invention consists of the novel features herein shown, described and claimed. j

Figure 1 is a fragmentary cross section of a street pavement and curbs drawn for the purpose of showing a street surfacing gage embodying the principles of my invention in use, the street surface delineator being shown in side elevation.

Fig. 2 is an enlarged fragmentary detail plan of the central portion of the delineator and showing the adjusting features, the view being taken looking in the direction indicated by the arrows 2 in Figs. 1 and 3.

Fig. 3 is a side elevationof the parts shown in Fig. 2 as seen looking in the direction indicated by the arrows 3 in Figs. 2 and 4.

Fig. 4 is a vertical cross section on the lines 4-4 of Figs. 2 and 3.,

Fig. 5 is an enlarged end view as seen looking in the direction indicated by the arrows 5 in Figs. 1 and 6.

Fig. 6 is a fragmentary sectional detail on a plane parallel with Fig. 1 and on the line 6-6 of Fig. 5.

Fig. 7 is a fragmentary side elevation looking in the direction indicated by the arrow 7 in Fig. 8.

Fig. 8 is a vertical cross section on the lines 8-8 of Fig. 7.

Referring to Fig. l, the gage plate 1 eX- tends from thecurb 2 to the curb 3 and is curved to fit the face of the proposed pavement 4. The gage plate 1 is carried by a rigid frame 5 and the ends of the frame are supported upon the faces of the curbs 2 and 3.

The frame 5 is adjusted to a'proper level relative to the upper faces 6 and 7 of the curbs 2 and 3 by adjusting the screws operated by hand wheels 8 and 9. The central portions of the gage plate 1 are connected to the central portions of the frame 5. The frame 5 is straight and the desired curvature of the gage plate 1 is adjusted relative to Specification of Letters Patent.

the frame 5 by screws operated by hand wheels 10 and 11 for the first quarters, by the hand wheels 12 and 13 for the second quarters, by the hand wheels 14 and 15 for the third quarters, and by the hand wheels `16 and 17 for the fourth quarters.

Referring to Figs. 2, 3 and 4, the frame 5 is made in two main pieces 18 and 19, the meeting ends of the pieces 18 and 19 being adjustably over-lapped to make the central portions of the frame. The portion 18 of the frame 5 consists of channel irons 20 and 21 placed back to back, spaced apart and rigidly secured together, and the portion 19 consists of channel irons 22 and 23 placed back to back, spaced apart and rigidly secured together, and the portions 18 and 19 are placed together at their inner ends and placed side by side with the channel irons 22 and 23 slidingly over-lapping so as to adjust the length of the frame 5.

A block 24 is placed between the ends of the channel irons 20 and 21 and secured in place by bolts 25. A bearing 26 extends upwardly from the block 24. A clamping bolt 27 lits in the bearing 26 and has a hook 28 extending across the top of the channel irons 22 and 23 and hooking over the channel iron 22 so that when a nut 29 is tightened the portions 18 and 19 are clamped together.

An adjusting bearing 30 is formed upon a block 31 fitting between the channels 20 and 2l and secured in place by bolts 32. In a like manner a clamping bearing 33 and adjusting bearing 34 are secured to the channel irons 22 and 23 and the clamping bolt 35 has a hook 36 engaging the channel 21.

A turn-buckle adjusting screw 37 has right and left threads 38 and 39 screw seated in the adjusting bearings 30 and 34 so that when the clamping bolts 27 and 35 are loosened the screw may be operated to move the bearings 30 and 34 to and from each other to adjust the effective length of the frame 5.

The gage plate 1 is formed in two pieces 40 and 41 and each piece is a flat piece of iron. The piece 40 lits under the portion 18 of the frame 5 and the piece 41 fits under the portion 19 of the frame 5. A T-shaped bar 42 is placed cross wise of the end of the piece 40 and secured in place by a rivet 43 and the arms of the bar extend through slots in the webs of the angle irons 20 and 21 so as to hold the end of the piece 40 in engagement withl the bottoms of the ends of the angle irons 20 and 21 and so asto allow the piece 40 to slide to a'limited extent relative to the channel irons.

In a like manner the piece 41 is slidingly connected at its end to the ends of the channel irons 22 and 23 by a T-bar 44 sliding in slots 45 and connected to the piece 41 by a riVet 46.

Referring to Figs. 7 and 8, a block 47 is secured between the channel irons 20 and 21 by bolts48. The adjusting screw 49 is screw seated through the block 47 and a swiveled comiection 50 is made `between the lower end fof the screw 49 and the gage plate 1.

The hand wheel 10 is fixed to the upper end' of the adjusting screw 49 so that when the hand wheel 10is operated the gage plate 1 is' raised or lowered relative to the frame 5. A strap of metal is bent to form the bearingnportion 51 through which the adjusting screw 49 is swiveled and the side bars ,52' and 53k extendingl downwardly from the bearing portion 51 past the frame 5 and secured. to the gage'plate 1.

Gagei'ndications 54 are formed on the face ofthe side bar 52 and a stationary gage indicator-55 is secured to the channel iron 2l so that as the hand wheel 10 is operated toraise or lower the gage plate 1 relative to theframe V5V the movement or location may be read upon the graduations 54 and 55.

InV a like manner the hand wheel 11 is mountedV on the frame 5 and connected to the 'gage .plate 1. The hand wheels 10 and 11 aresubstantially equal distances from the center ofthe frame 5 and from the center ofthe proposed rpavement and the constructions are substantially alike- In a like manner the hand wheels 12 and 13 aremountedupon the frame 5 and connected to the gage plate 1, the constructions being the same as the constructions of the hand wheels 10 and 11 except that the parts arearranged for a greater depth from the framev 5 to ther gage plate 1. The hand wli'eels114v and 15 aremounted in the same way and adapted for a still greater depth.

vReferring to Fig. 6 the hand wheel 16 is fixed to theadjusting screw 57 and the adjusting screw voperates through a swivel bearing 58'and through a block 59 and isconnected yto the gage plate 1v by a swivel 60. The hand wheel 17 is connected to the opposite end of the frame 5 and to'the hand wheel`16 in the same manner as the hand wheel 16 and the adjusting screw 61 is connected to the gage plate 1 the same as the adjusting screw 57.

Referring' to Figs. 5y and 6; an arm 62 is fixed .to the endof the frame 5 andextends upwardly a considerable distance. Gage plates 63and 64 are secured to the front Yface of 'the Varm 62. An extension arm 65 extends upwardly'from the arm 62 in line with; te@ sage-Plaie? @Bead 64 and* the swivel bearing 58 is fixed to the extension arm 65.

A sliding gage 66 is slidingly mounted between the gage plates 63 and 64 and the lower end of the sliding gage 66 is fixed to the gage plate 1 so that as thehand wheel 16 is operated the gage plate 1 will go up and down and the location or movement may be read upon the graduations of the gage 66 and the graduations 67 on the rigid gage plate 63. l

In a like manner the hand wheel 17 operates a gage construction 68.

A bearing 69 extends horizontally from thefupper end of the arm 62. The hand wheel 8 is fixed upon the upper end of the adjusting screw 70, the adjusting screw 70 is swiveled through the cap plate 71 and screw seated through the bearing 69 and swiveled in a base plate 72.

The bearing 69 is mounted to slide up and down between posts 73 and 74 and the posts are held rigidly together in vertical parallel positions by the cap plate 71 and the base plate 72.

Forked arms 75 and 76 extend forwardly and backwardly from the lower ends of the posts 73 and 74 and supporting wheels 77 and 78. are mounted in the forks and run uponr the face of the curb 2 so as to support the frame 5 and carry the frame up or down the street.

Graduations 79 are formed upon the post Y7 3 and graduations 80 are formed upon the face of the bearing 69 so that as the frame 5 goes up or down by the operation of the screw 70 and the hand wheel 8 the movement o r location may be read upon the graduations.

In a like manner the hand wheel 9 is mounted in a construction' 81 to run upon the surface 7 of the curb 3 and support the other end of the frame 5. The screws controlled by the hand wheel 8 and 9 are adapted to providel a considerable u and down movement for the frame 5 so tlat the surface gage may be used for gaging all of the different operations involved in making the street.

The frame 5 may be lowered and the gage plate 1 set to gage the grade of the street. Then the frame and gage plate may be raised to gage the bottom layer of the pavement as they are laid one on top of the other.

lit is thought that the various uses and operations are obvious and will be understood from the drawings and from the foregoing description.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

1. A street surface delineator comprising a supporting frame, means whereby the supporting frame may be adjusted lengthwise,

ineans for supporting the ends of the supporting frame, a flexible gage plate mounted below the supporting frame, adjusting screws connecting the gate plate to the sulpporting frame at various points so that t e curvature of the gage plate may be adjusted relative to the straight supporting frame, and indicators for showing the adjustments.

2. A street surface delineator comprising a straight supporting frame adapted to reach across a street, means for supporting the ends of the supporting frame upon the curbs, means for adjusting the frame up and down, means for adjusting the length of the frame, a flexible gage plate below the frame, and adjusting screws arranged along the frame and connected to the gage plate for adjusting the curvature of the gage plate relative to the straight frame.

3. A street surface delineator comprising a supporting frame adapted for adjustment longitudinally, carriages for supporting the ends of the frame and adapted to run upon curbs, means for adjusting the frame up and down upon the carriages, a flexible gage plate below the frame, and adjusting screws arranged along the frame and connected to the gage plate for adjusting the curvature of the gage plate relative to the straight frame.

In testimony whereof I have signed my name to this specification.
